'WEAVING APPARATUS.

To @ZZ whomz't may concern:

Be it known that I, lWILLIAM F. GRUPE, a citizen of the United States of America, residing at Hudson Heights, county of Bergen, State of New Jersey, have inventedy certain new and useful Improvements'in Weaving Apparatus, of whichv the following is a specification. v l

This invention relates to weaving apparatus and particularly to the harness and shafts of weaving apparatus. f

More particularly, the invention relates to harness comprising heddles, eyes having an open side and means coacting to close the open side of the heddle. In the more preferredsforms of the invention, means are provided for guiding and maintaining the tially a common plane.

Further features and objects of the invention will be more fully understood from the following descriptionl and accompanying drawings, in which-d l Figure 1 is a front vertical elevation of a shaft and harness comprising my invention;

Fig. 2 is an end vertical elevation; and

Fig. 3 is a sectional elevation on line 3--3 of Fig. 1.

Referring to the drawings, the embodiment of the invention shown therein is of the type adapted to be supported by suspension from a single shaft 1, although the invention, as will appear, is applicable for other types of harness and shafts.

Each heddle 2 is provided withthe eye 3 having an open side 4. Preferably, each heddle 2 is formed of flat wire or plate of kmetal or other suitable material, the eye 3 Means are provided for guiding and maintaining the heddles in a substantially common plane, as by a slotted frame, the heddles being disposed in the slot thereof, and Side by side. In the particular embodiment indicated in the drawings, I have shown two sets or groups of heddles arranged alternately in substantially a common plane, and guided in reciprocating movement vin such plane by .the slotted upper guiding member Specification of Letters Patent.

similar laterally extending portion 12-projecting in another direction, to which is attached the cord 13, similar to cordl `5, and

` extending about the other Shaft 14.

F or other number of sets of heddles, the arrangement of such sets of heddles in thek desired common planeror planes is similar and the number of shafts conform to the number of the sets of heddles.

Such upper and lower slotted frame members may be coupled :as a unit by the side cords or bars 15. The slotted frame is suspended from any suitable fixed support such as a bar or the likeby means of the side cords or barsv 17; vFor the purposeiofholding the slotted frame in vertical alinemenn. the weightsjlS may be employed as by Sus-V pending the same by the cords 19 from the lower slotted member '9.

For simplicity of attachment of the op.- erating means 5, 13, to the respective `heddles 10, 11, of the respective sets, each heddle may be recessed as by the provision of the perforations 20.

Thus, upon reciprocation of the shafts 1, 14, the corresponding sets of heddles are reciprocated within the guiding frame 8, 9, the guiding frame being held in relatively fixed position, whereby all heddles are reciprocated in substantially a common plane. It will be further noted that the open Sided eyes of the respective sets are maintained closed during the stage of reciprocation of the heddles. Preferably, each slotted frame member 8, 9, vis formed of similar outside fiat bars 21, 22, held spaced apart by means of the end spacing blocks 23, each such block 23 being held in position by means of the removable bolt 24 having a head 25 at one end and the removable nut 26 at the opposite end.

Upon completion of the weaving operation, the warp threads are withdrawn from the open sided eyes 3 and the frame members 8, 9 removed by opening the bolts 24 and separating the respective frame bar members 21, 22, while leaving the warp thread intact. The ready Withdrawal of they Warp threads from the heddles `and the removabilit of the heddles andthe iding frame romtthe'warpthreads, is a van-1 the Warp threads.

Inl general, the invention is also applicable in all Weavingoperations for Weaving 4With agiven'number of sets of heddles -until a certain Ystage is reached, then withdrawing the warp threads fromsuch sets'ofl heddles and,` if desired, substituting the different' set of 'heddles and eontinuing'the Weaving under the replaced conditions, as desired.

Whereas I 'have 'described my inventionby reference .to speciiciforms thereof, it Will'be understood that' many changes and modifications ,may be made Without departing' 'from the spirit of the invention, as dened by the appended claims.
